My invention relates to a valve mechanism and pressure recording deviceespe- 'cially adapted for i'l'seinlinlating prieninatic tires ofautomobiles and the lilie,'ai1d has tor itsolijert to provide a (Jnielcacting i'i'iain|all operatei-l valve eqiiippi-zd with. a lii'eniireginge. which will forni a con'neetirni fromtheenflof an air-hose totheralve tiihe of a pneumatic tire, hy simply pressing the;

The supplying ot air to the patrons of a garage for inflat-ing tires isan item of con; siderablc expense and vis usually a service for which nocharge is made. This ex pense is unwarrantedly increased by the wastefulconsumption of air.

Ordinarily a hose of sufficient length to extend from the Shut-ott valvein the airline to the four wheels of an automobile is employed, and asthis takes the user some little ,distance from the shut-oit' valve, itis found more convenient to permit the air to wastefnlly blow whilechangin from one wheel to another than to wal', each time, to theshutoff, or an eifort is made to confine the air bv kinking the hose, s.'practice result-ing in its early destruction. By the use of my device agreat saving in the consumption of air is effected, and the frequentrenewal o f the hose isevoided.

The device not only indicates the pressure in the infiated tire.guarding against bursty ing from over-inflation, but as the air pressurein the chamber 15 compresses the packing ring rmiy. against the pin 18,when the device is notin connection with the valve tube of a tire, thepressure on the air line or in the reservoir can be immediatelydetermined by simply depressing thc lever 13, making unnecessary a tripto the com presser, which is uaualliY located at Some distant point inthe garage.

(lne of its` greatest advantage;` lies in the fact that the entiredevice is relatively small, and capable ot' being held in andmanipulated by one hand to perform its several functions. PositionsordinarihT diilir'ult to reach are thus rendermi comfortably andisonvenientllvaccessible. B'v grasping the valve. with the lever handlelying in the "palm, the automatically formed airtight slip oonncctii'in'is readily forced over the en d ot' the tirevalve tube, and, without reluasingthe hold ouchanging the position offthehand, the valve isoperated by simply contracting and relaxing the grip and it wi lv heobserved that thev necessary pressure to open the 'valve is applied inthe direction ot thrust in 'making the automatic slip con neetion.

The 'prest Having thus clearly described my invention, what I claim asneit7 is:

l, Ina device of the class set forth, a T fitting; a pressure gageattached to one of the passages thereof; a tire-nipple engagingY deviceconnected to the passage ot the fitting opposite the pressure gage andprovided with a valve device adaptedtc malte an airtight connection withthe nipple body and also adapted to close by internal air `pressure whenthe device is disconnec'teil"from the nipple; a valve caslng'attached tothe remaining,r passage of said fitting and provided with means forconnecting it with au air-hose; and a manuallyoperated reciprd eatingvalve mounted in said casing between the fitting connect-ion and theair-hose connection, said valve being reciprocable on a lineI parallel'with the tire-nipple engaging device and adapted to open in thedirection of thrust in making connection with a tire valve.

2. In a valve of the class described, a three-Way fitting; an attachmentsecured to said fitting affording communication to a source ofaix-supply; a connecting member and a. recording gage secured to saidfit.- ting; in combination with means adapted to establish communicationfrom said Source of cir supply to said connecting memhe'r and to saidrecording gage, said conneetingmember 'being provided with autometicmeajns 4whereby connnunitaition may be established between thesource of air su pplj'- and said `recording gage without the escape ofair from the connecting member.

3.111 a valve ,of the clase described, a valve body provided with aninlet and an outlet; means adapted to establish commit nication from asource of air supply to said inlet; and an automatic slip connectioncommunicating with said outlet comprising a body portion having avertically extending tire-valve-opening pin aliixed centrally thereofand a packingV ring havingr a .raised contrai portion surrounding saidpin capable of being expanded from said pin forming an air passage toand an air-tight''connecton with a tire valve and of being conipressedagainst said pin forming an airtight closure when disconnected from atire valve.
